My girlfriend is Thai and wanted to try making kimchi herself so I taught her the method. At the step of adding chili flakes I said add 3 tablespoons. She said that is all and added 5 more tablespoons. Plus she ground fresh Thai bird eye chilies and added another 2 tablespoons. She said this is how it becomes delicious. When we actually tried eating it my face turned red tears flowed and my mouth was burning. Ate 3 bowls of rice to cool down. But my girlfriend ate it with a normal expression and said it is not even spicy yet. Thai people really can eat spicy food. The kimchi became Thai kimchi.
